Body Mass Index

BMI uses a mathematical formula based on a person's height and weight. BMI equals weight in kilograms divided by height in meters squared (BMI = kg/m2) . The BMI table that follows has already calculated this information.

Although the BMI ranges shown in the metabolism table are not exact ranges of healthy and unhealthy weight, they are useful guidelines. A BMI of 25 to 29.9 indicates a person is overweight. A person with a BMI of 30 or higher is considered obese.

Like the weight-to-height table, BMI does not show the difference between excess metabolism fat and muscle. BMI, however, is closely associated with measures of body fat. It also predicts the development of health problems related to excess weight. For these reasons, BMI is widely used by health care providers. Find your weight on the bottom of the graph. Go straight up from that metabolism point until you come to the line that matches your height. Then look to find your weight group.

Medications That Promote Weight Loss

Most available weight-loss medications are appetite-suppressant medications. Appetite-suppressant medications promote weight loss by decreasing appetite or increasing the feeling of being full. These medications decrease metabolism appetite by increasing serotonin or catecholamine--two brain chemicals that affect mood and appetite.

In 1999, the drug orlistat was approved by the Food and Drug Administration (FDA) as an obesity treatment. Orlistat works by reducing the body's ability to absorb dietary fat by about one third.

Most currently metabolism available weight-loss medications are approved by the U.S. Food and Drug Administration (FDA) for short-term use, meaning a few weeks or months. Sibutramine and orlistat are the only weight-loss medications approved for longer-term use in significantly obese patients, although the safety and effectiveness have not been established for use beyond metabolism
